The Topic of War and Peace Critical Essay Is Filled With Harmful Ideas

The Topic of War and Peace Critical Essay Is Filled With Harmful IdeasAfter reading this on essay, I felt it a bit disingenuous for you to read the same article, yet as if you are expressing similar views, which is the problem with this argument. It seems you are attempting to be critical of the topic of war in war and peace critical essay. Not only do you do this, but you are also following in the footsteps of your critics, who when they have the opportunity to choose to be a social justice warrior, instead of being a problem solver. I am not going to discuss that topic here because the topic of 'solution' is already addressed, in a very positive manner.They are generally moderates and progressives, who would like to do what is best for mankind, but they can't or won't do so, instead they become part of the social justice warriors. This is probably one of the worst types of people to follow, as they are all about using and abusing people, while making themselves look good at the sam e time. So, I am afraid that you will follow in their wake. Do you follow in their path?For that matter, you need to know that the best way to deal with an issue like this is to not be polarized, however, you also need to find a middle ground, as well as a solution. One solution is to seek out the truth, and then accept it. Two different methods, I see. Are either of these methods useful? Both could be used, as I don't think there is any such thing as one or the other.This dilemma is particularly relevant to a situation like this, where the author knows that she doesn't want to agree with the idea of war in war and peace critical essay, yet the author is trying to find a middle ground, and the author wants to find a solution, but can't figure out where to start. A dilemma indeed. If one of the options is right, then we all can make use of the option, and if the options are both wrong, then both of us lose, or we could lose for no reason at all.Indeed, I suspect that if the writer ha d a social justice warrior following her, that the writer would follow the dictates of their political and religious groups. You see, we all live in a world where we are supposed to follow whatever they say. That's the way it goes.I think we all need to just take a look around us and ask us, if we are talking about a war and peace critical essay, which one would be better, which one does the best job, or is it both of them? It seems like the writers is more interested in finding a solution, but doesn't have the solution, but would rather spend her time doing that, than solving the problem. Then she adds the social justice warrior rhetoric to that, and then she puts a deadline on how long she needs to solve it, but she didn't offer a solution, or a solution to the problem.The reality is that we all need to take a look at our lives, and realize that we really can't fix anything, but we can change the things that we want to change. So, do we really want to do that? Or do we want to set deadlines and put barriers in place?We should really ask ourselves if we want to be a social justice warrior, and then if we don't like the answer we come up with, then maybe we should be a real problem solver. Maybe we need to continue looking for solutions, and if we don't find any then maybe we should stop looking. Maybe that's the way to go.

Finding Resources For Writing SSAT Essay Sample

Finding Resources For Writing SSAT Essay SampleTo help your students prepare for the SSAT, you can use sample SSAT essays to help them develop their own. You may also be able to help them find resources to study for the exam and their instructors should also be able to assist them with the writing process. One thing you should do is to give your students as much guidance as possible about how to properly prepare.There are two main aspects of writing a successful essay. The first part will be the content and the second is the process of organization. You should never be concerned with the content itself. It should be based upon the goals you are trying to achieve and should highlight the topic that you believe your student has an interest in.First, you can use parenthesis to help your students organize their thoughts in their SSAT parents essay. By using parenthesis, you can connect ideas and put them in logical order. Using parenthesis not only provides structure to the writing but c an also help the reader understand the exact content. There are several ways to use parenthesis. Some are:Research: Beginning by using parenthesis around the research information, the students should have written the following: 'This project was organized by Karen before her son started at school.' 'After much research, Ann decided she wanted to spend more time with her family.' All this is done in parenthesis.Testimonies: Beginning by using parenthesis around the testimonial, the students should have written the following: 'When Taylor told Ann she was going to be a mother, she thought about some of the things she has learned about children as a friend.' 'Taylor had never thought about her children before that moment.' All these are written in parenthesis.Conflicting information: Using parenthesis to express conflicting information can help create clarity between the students and get them thinking logically about the specific objectives of the project. You can use parenthesis to wr ite the subject phrase, the complete sentence, and the entire sentence. The students should write what they want to say first, then place the parenthesis following it. This way, it will be easier for them to remember the exact subject and complete sentence.Problem solving: Again, using parenthesis to express this problem, the students should have written the following: 'Alice went to a meeting on the third Tuesday of every month.' 'Jane finished her project on Friday.' All these are written in parenthesis. You should place the parenthesis around the time the project was completed. At the end of the sentence, the students should add a period to show they are done writing.After your students have completed their main idea, you can use the parenthesis to tie everything together. In order to use the right type of parenthesis, you should look for the ones that tell you what they do, where they are located, how they are used, and the end of the sentence. These are some examples of SSAT pa rents essay samples that you can use to help your students write their own.

The Indirect Iodimetric Analysis Ascorbic Acid free essay sample

I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis, the oxidizing agent can be determined by a different means than titrating directly with standard iodide, because a high concentration of I- is needed to form the I3- complex. In this type of analysis, excess iodide is added to the oxidizing agent, and the triiodine is titrated with stand thiosulfate. This indirect analysis finds the number of moles of ascorbic acid based on the known number of moles of IO3- and subtracting half the amount of moles of the thiosulfate solution. II: Equations: Iodate with Iodide: IO3- + 8I- + 6H+ ? 3I3- + 3H2O Thiosulfate with Triiodide 2S2O32- + I3- ? S4O62- + 3I- Ascorbic Acid with Triiodide C6H8O6 + I3- +2H2O ?

Conclusion: After completing three separate methods to determine the percent weight of ascorbic acid in a sample, in the manual titration the percent weight was 51. 45%. The semi-manual method gave a percent weight of 51. 40%, and the automatic titration gave a percent weight of 50. 18%. Averaged together, giving a percent weight of 51. 01% and a standard deviation of 0. 719 and an RSD of 14 ppt. A possible systematic error that could have occurred would have been while doing the manual titration to not wipe the tip of your 25 mL pipet. This would have caused the calibrated amount to not have been correct and you would have added a falsely high amount of potassium iodate. This would have given a value of moles I3- higher than what was actually given. This is turn would create a larger value for the moles of ascorbic acid and you would get a higher percent weight. Another possible systematic error would be if the automatic titrator was improperly calibrated and it caused the volume dispensed to be larger than what was shown. This would have given an underestimation of the end point. For example, if the machine showed the it had reached the end point at 15. 00 mL but in realty the machine had dispersed 15. 02 mL. , which would lead to a number of moles of S2O32- that are lower than what was actually required, which would in turn give a lower percent weight of ascorbic acid and be falsely low. VI: Questions: 1. Explain the difference between iodimetric and idometric methods of analysis. Why is this experiment classified as an indirect iodimetric method? Iodimetric uses reducing agents to be determined by direct titration with standard I3-. Examples are As(III), sulfide, cyanide etc. , which contain oxidizable functional groups. Whereas idometric is used for the determination of oxidizing agents. Excess iodide is added to the oxidizing agent and the triiodide that’s produced is titrated with thiosulfate. This experiment is classified as an indirect iodimetric method because since we are measuring content of ascorbic acid through the known moles of thiosulfate and I3-, the method becomes indirect but it is also idoimetric because we are determining an oxidizing agent. 2. What is the function of the KIO3 solution? Explain how the preparation of this standard solution differs from the preparation of the standard NaOH solution used in the Soda Ash experiment. Iodate was used because in the idometric analysis, a high concentration of I- is needed, so excess iodine is added to the iodate to form the triiodine which is then titrated with thiosulfate. This differs from the soda ash experiment because in the soda ash experiment a primary standard (KHP) was used. 3. Use a balanced net ionic equation to explain the purpose of the KI in this experiment. Why must KI be present in excess? IO3- + 8I- + 6H+ ?  3I3- + 3H2O KI is in excess because a high concentration of I- is needed to form the triiodine which then allows the method to proceed with idometric analysis, where the I3- can be titrated with thiosulfate. 4. What is the function of thiosulfate? Write the balanced net ionic equation for the reaction of thiosulfate and triiodide. What pH range is required for this equation to hold? 2S2O32- + I3- ? S4O62- + 3I-. S2O42- is used for titration after it has been standardized which can be determined by the equation moles of ascorbic acid = moles I3- ? (moles thiosulfate). This complex is oxidized to S4O62- as log as the pH is below 9. 5. Describe the preparation and standardization of the thiosulfate solution including all special procedures. The solution is made from Na2S2O3 5H2O, but since it is not a primary standard, it must be standardized. The solution has the potential to be oxidized by atmospheric oxygen, so deionized water which is bubbled with nitrogen prior to the solution preparation. Adding a few drops of chloroform prevents bacteria which can cause decomposition. 17 g of Na2S2O3 5H2Om was added and filled with water that has been bubbled with nitrogen and 0. 05g Na2CO3. The solution is then mixed and the chloroform was added. Three spate flasks were used for standardization. Each flask contained excess solid KI. For the titration, when the color turned pale yellow, the starch indicator was added and the titration was complete when the blue color disappeared. 6. What is the indicator for titrations involving triioidine ion? Why is the indicator added just prior to the end point? When the yellow color turns pale, the helical amylase component of soluble starch is added. This indicator must be added after most of the triiodine has reacted because in large concentrations, the stable complex remains even after the end point is passed. 7. Give the common name and molecular formula for ascorbic acid. Write the balanced net ionic equation for the reaction of this compound with triiodide ion. The common name is Vitamin C and it has a molecular formula of C6H8O6. C6H8O6 + I3- +2H2O ? C6H6O6 +3I- + 2H3O+ 8. Explain what is meant by potentiometric end point detection. Describe data analyses by first and second derivative plots. Potentiometric end point detection, the end point is determined graphically and titrant is added in increments and the potential is measured. The first derivative is the change in voltage divided by the change in the titrant volume on the y-axis and it is plotted against the titrant volume midway between the two points. Where the slope is the steepest is the end point. The second derivative is the change in the first derivative divided by the change in the titrant volume midway between two points, on the y-axis and the average value of the midway titrant volume on the x-axis. The end point is where the graph crosses zero. 9. Explain the difference between an indicator electrode and a reference electrode. What items serve these functions in this experiment. An indicator electrode responds to changes in the activity of one of the ions in the solution, since it is impossible to measure a single electrode, a reference electrode is needed. The reference electrode remains constant, any changes are due to the indicator changes. 10. A possible source of systematic error in this experiment is partial decomposition of the thiosulfate solution. Suppose that decomposition occurred after the thiosulfate was standardized, but before it was used for analysis of ascorbic acid. Would the wt% ascorbic acid be falsely high, falsely low, or unaffected? Give all the reasoning to justify your answer. If the thiosulfate had decomposed after it had been standardized, it would have required more milliters of solution to titrate and obtain the same amount of moles since the concentration had been decreased. With more titrant being added, you are going to get a number of moles that is greater. Since to obtain the moles of ascorbic acid, you subtract the moles of the thiosulfate (divided by 2) from the moles of the IO3- you are subtracting a larger number and you are going to obtain a smaller number for the moles of ascorbic acid, thus the %wt would be falsely low.
